We lower control rods to cool or shut down a nuclear reactor. Lowering control rods allows those rods to absorb more neutrons, and this limits or shuts the fission chain down.
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
They are used in nuclear reactor to control the rate of fission of uranium and plutonium. Because these elements have different capture cross sections for neutrons of varying energies, the compositions of the control rods must be designed for the neutron spectrum of the reactor it is supposed to control.
By the control rods and by the moderator.
The core of the nuclear reactor includes:nuclear fuel elements (composed of the fuel meat covered with cladding)reactor coolantreactor moderator (for thermal reactors)control elementsmeasuring instrumentsstructural and support structures
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
Boron is used inside a nuclear reactor inside a control rod which is used to 'soak' up the neutrons inside the nuclear reactor, a control rod can be used to control the rate of fission inside a nuclear reactor.
The number of control rods in a reactor will vary with the size and the design.

nuclear reactor control rods
In dealing with a nuclear reactor SCRAM stands for Safety Control Rod Activator Mechanism. Nuclear reactors can be quite dangerous.
The control rods inside a nuclear reactor are made out of Boron.

Sorry, in any real nuclear reactor every control rod probably absorbs many moles of neutrons per second while the reactor is operating.
